Title: Near-field optical recording device
Inventor: KIM SU GYEONG
IPC: G11B9/12
Filed: 2000-12-28
Abstract: PURPOSE: A near field optical recording device is provided to clean the surface of a lens when the surface of the external operation lens loaded on a slider is exposed to an external, upon near filed optical recording or reproduction, while interacting with the surface of a recording medium. CONSTITUTION: A cleaner(35) is located on a locus on which a slider(31) moves. If a cleaning operation is inputted from a user or automatically at predetermined intervals, a VCM(Voice Coil Motor) is driven to locate the slider on an upper surface of the cleaner.
